helps alot im this is my first outdoor/ more than one plant. so im really on the fence with every thing i have done so farYea I would say leave then alone uunless your dealing with mold and it's a real bushy plant then I would say thin it out jus think of each leaf a solar panel for a city the more solar panels the more energy the more energy to grow in this case! But when your dealing with mold it changes a little bit that's how I look at it. Hope this helps
